Abstract
The utility model relates to a strengthening structure on tire bead of an all steel cord truck radial tire. The strengthening structure on tire bead is suitable to be installed on the tires of trucks, buses, trailers etc., which can markedly increase the capability and service life of the tires. The strengthening structure essentially comprises a bead wire, a radical carcass ply, a compound filled rubber made of two rubber materials with wide capacity distinction, a strengthened story of the carcass ply of strengthening structure on tire bead and a compound fiber/rubber strengthened story.
Description
The utility model relates to a kind of position, rim of the mouth heavier-duty structure of full steel wire heavy load radial tire.Adopted the tire of position, the utility model rim of the mouth structure, be applicable to the installation truck, city motor bus on the vehicles such as trailer, can effectively improve the load-bearing capacity and the life-span of tire, and this utility model is to belong to the tire production technical field.
At present, the narrow wirecord fabric enhancement Layer of one deck that possesses outside it after position, the rim of the mouth structure of full steel wire heavy load radial tire is overturn by steel bead wire, carcass cord and carcass cord is substantially formed, because the upper extreme point of the outer end points of carcass cord and the outside close together of tire and this end points and steel cord enhancement Layer is too concentrated, the hardness of bead apex is on the low side in addition, thereby cause tire under high-load operation, the damage at tyre rim position takes place easily, and the life-span of tire reduces.
The raising in position, rim of the mouth life-span can be by improving the intensity at position, rim of the mouth along increasing the reinforcement cord in the length of carcass cord after the tyre bead upset, the Chinese patent 00207683.7 of perhaps having is described, the steel bead wire infantees width that adopts is bigger, the steel bead wire infantees extends to the inboard of tyre bead, being equivalent to has increased one deck steel bead wire infantees again in the inboard of tyre bead portion, reaches the purpose of raising tire life with the very property of further raising tyre bead portion.
The purpose of this utility model is to propose another kind of position, the rim of the mouth life-span of full steel wire heavy load radial tire and the method for load-bearing capacity of strengthening.
Position, the heavier-duty rim of the mouth structure of the utility model full steel wire heavy load radial tire is to realize like this.This position, rim of the mouth structure mainly is made up of steel bead wire, composite filled adhesive tape, carcass wirecord fabric, position, rim of the mouth steel cord enhancement Layer, fiber/rubber combined enhancement Layer.Composite filled adhesive tape is extruded by rubber combined extruder production, the top of composite filled adhesive tape is the rubber composition of low shore hardness, the below is the rubber composition of high shore hardness, the hardness of the rubber composition of high shore hardness is higher than the hardness number of the rubber composition that hangs down shore hardness between 20～40, and guarantee evenly excessively at interface between the two; This position, rim of the mouth structure is from section, composite filled adhesive tape is on the top of steel bead wire, the upper extreme point position of composite filled adhesive tape is near the maximum axial width position of tire, near the rubber composition that shore hardness is low in the close bead apex of radial carcass carcass plies its end points after the steel bead wire bottom reversed, its end points is lower than the upper extreme point of composite filled adhesive tape, and the position of end points is positioned at apart from the distance in the tire outside and is 1/3～1/2 of this end points virgin oral area position thickness; Constitute the outside that position, rim of the mouth steel cord enhancement Layer is positioned at casingply by steel cord and rubber composition, the steel cord of position, rim of the mouth steel cord enhancement Layer and the angle of radial carcass cord in the end-point distances of 50 ° of 80 ° of body cords between 5mm～25mm, the lower extreme point of position, rim of the mouth steel cord enhancement Layer is lower than the lower extreme point of fiber/rubber combined enhancement Layer, fiber/rubber combined the enhancement Layer that has one deck to strengthen by one deck fibercord at least in the outside of position, rim of the mouth steel cord enhancement Layer, the upper extreme point of fiber/rubber combined enhancement Layer is the highest can to reach the maximum axial width position that the position is close tire, and the minimum steel bead wire bottom of can passing through extend to the inboard, rim of the mouth.
The full steel wire heavy load radial tire that adopts position, reinforcement described in the utility model rim of the mouth to make; greatly reduce the stress of position, rim of the mouth carcass cord end points, position, rim of the mouth steel cord enhancement Layer end points; simultaneously because the protective effect of the compound enhancement Layer of fiber rubber; avoided tire in use circumferential crack to occur, effectively raised the service life and the load-bearing capacity of tire at the position, rim of the mouth.
Figure of description is the sub-port structure section-drawing of the utility model optimum implementation, 1. steel bead wires among the figure, the 2. rubber composition of high shore hardness in the composite filled adhesive tape, the 3. rubber composition of low shore hardness in the composite filled adhesive tape, 4. carcass wirecord fabric, 5. position, rim of the mouth steel cord enhancement Layer, 6. fiber/rubber combined enhancement Layer.
The best exemplifying embodiment of the utility model as shown in the figure, composite filled adhesive tape is through the complex extruder extrusion molding, high 29 values of hardness of the rubber composition of low shore hardness in the composite filled adhesive tape of hardness ratio of the rubber composition of high shore hardness in its composite filled adhesive tape, composite rubber strip and steel bead wire are combined into one through applicator, the compound enhancement Layer of fiber rubber is compounded in the limit portion of sealing layer in the production of tire seal layer, the carcass cord, other associated components of position, rim of the mouth steel cord enhancement Layer and making tire are produced the full steel wire heavy load radial tire with this heavier-duty sub-port structure after vulcanizing through the make-up machine moulding of once-through method full steel wire heavy load radial tire and by vulcanizer, the angle of its rim of the mouth steel cord and radial carcass cord is 68 ° of 48mm, the distance that the end points of carcass cord is higher than the upper extreme point of position, rim of the mouth steel cord enhancement Layer is 12mm, position, the rim of the mouth thickness at the end points place of carcass cord is 21mm, the outer lateral extent of its end-point distances tire is 9mm, account for 2/5 of this virgin's oral area position thickness, the distance that the upper extreme point of the compound enhancement Layer of fiber rubber is higher than the end points of carcass cord is 26mm, and the lower extreme point of the compound enhancement Layer of fiber rubber is higher than the lower extreme point 28mm of position, rim of the mouth steel cord enhancement Layer.
